اکثر پوچھے جانے والے سوالات

What's the Rule of 9s for %TBSA?

Head/neck: 9%, Each arm: 9%, Chest: 18%, Abdomen: 18%, Each leg: 18%, Perineum: 1%. Measure by body part involvement. Children differ (head 18%, leg 14%).

Why Lactated Ringers (LR) vs normal saline?

LR isotonic, contains potassium, more physiologic. NS can cause hyperchloremic acidosis. LR preferred in burn resuscitation (evidence-based). Monitor urine output (goal 0.5 mL/kg/hr adults).

Is Parkland formula always enough?

Starting point; adjust based on clinical response. Goal: urine output 0.5 mL/kg/hr (1 mL/kg/hr if inhalation injury). May need more in lightning strike, electrical burns. Serial labs essential.
